STANCHION-SUPPORT.

Specification of Letters Patent.

Patented J une 1, 1920.

Original application iiled February 18, 1919, Serial No. 277,778. Divided and this application filed July y To all whomA t may concern.'

Be-it known that I, JOHN M. B. Lnwrs, a citizen of the United States residing at Lynchburg, in the county of ampbell and State of Virginia, have invented certain new and useful Improvements in Stanchion- Supports, of which the following is a specilication.

This invention relates to supports for animal stanchions and has for its object the provision of such a support which allows a limited amount of freedom to the animal.

A further object is the provision of such a support which will maintain the alinement of the stanchion with the stall.

A still further object is the provision of a support which may be readily disengaged by the attendant but impossible of release by the animal.

These and other objects I attain by the combination and construction shown in the accompanying drawings, which will be considered in an illustrative and not a limiting sense, and in which:

Figure 1 is a front elevation of a stanchion embodying my device;

Fig. 2 is a side elevation thereof;

Fig. 3 is an enlarged front elevation of the upper end of the stanchion, parts being broken away;

Fig. 4 is a section on the line 4-4 of Fie- 3;

Fig. 5 is a section on the line 5-5 of Fig. 4;

Fig. 6 is a detail section, taken on line (iw-6 of Fig. 4;

Fig. 7 is a detail Section, showing a slightly different form of attaching member; and

Fig. 8 is a detail section.

In the drawings, wherein f or the purpose of illustration is shown a preferred embodiment of my invention combined with the stanchion forming thesubject-matter of my copending application No. 277,778, filed February 18, 1919, which has since become Patent No. 1,329,417 dated February 3, 1920, of which this application is a division, the numeral 10 designates the oppositely arranged arms or sides of the stanchion. These arms are preferably pivoted, at their lower ends, as shown at 11, to a U-shaped impeding element 12.

The arms 10 are'preferably tubular and at their upper ends, receive coupling-plugs Serial No. 311,289.

tions of this support-bar are curved in arcs of circles which are concentric with the pivots 11, as shown. i

The support-bar 17 is provided at a point preferably equi-distantly spaced from the ends thereof with an opening 18, which is preferably formed square in cross section for receiving a square portion19 of a suspension element 20. Above the supportebar 17, this suspension element has a shoulder 21, and below it a head 22 is formed by flattening or hammering the end of the portion 19. The suspension element 20 is provided at its upper end with a flat portion 23, adapted for insertion within a lower inverted approximately U-shaped link 24, and apertured for pivotally receiving a bolt 25, passing through apertures 26 in the lower link 24. This lower link has an upper transverse portion 27, extending within and transversely of an upper link 28, having inclined or cam faces 29, and a groove 30, receiving the transverse portion 27 as shown. It is thus seen that should the stanchion be turned upon its longitudinal axis the support-bar will turn the supporting element 20, whereby the link 24 will cause its transverse portion 27 to ride upon the cam faces 29. As soon as the stanchion is released, these cam faces will automatically return it to the proper transverse position.

The upper link 28 is provided with a transverse member 3()a and an opening or notch 30,'near and beneath the transverse member 30a. The transverse member 30 is adapted for insertion within a head 31, of an upper supporting member, carried by a shank 32. The head 31 has a cylindrical opening 33, having a contracted upper opening 34. When the upper link 28 is inverted, so that the opening or notch 30 will receive the jaw 35, the transverse portion 30a may be inserted within the opening 34, subsequently of which the link 28 is swung downwardly. It is thus seen that it will be impossible for the link 28 to be separated from the head 31 until it is again inverted, but this link is free to partake of restricted swiiging movements, longitudinally of the sta The shank 32 is adapted to be adjustably mounted Within an opening 36, formedv in a support block-37.4 The shank 32 also carries spaced pins'38, for insertion Withina groove 39, which is horizontally arranged. The shank 32 may be inserted Within theopening 36 When the pins 38 are positioned to enter the groove 39, and theshank 32 is thenA turned' Vso lthat these pins assume a vertical position, thereby :positively preventing' lon` gitudinal displacement of the shank." `The shank however lis free to partake of slight turning movement. irllie' support block 37 is secured to pipe rail 40 byl a U-shaped member 41,`asf`shoW'n. WVhen the rail 40"is not used, a beam 42 may be substituted therefor, (seeFig. 7) andthe support block 39 will 'thenbe equipped with aflat base 43 apertured for receiving bolts 44,'v as 'shown'.

lMeansf'are; 'provided to shift the 'arms 10 to the opened-and Closed positions', comprislever 45, there is'an extension 51,' preferably formed integral therewith, andthis 'exten sion is equipped with a tubular head 52. vThis tubulari head slida'bly vrreceives avertically movable bdlt"5`3,adapted toy enter a verticalfop'ening 54 in 'thetransverse "support-bar 17L The bolt l53 has a 'longitudinal slot 55,' receiving 'a transverse pin56, which preventsits displacement. f 'l At'its "lower end, the impeding element l2 has suitableconnection With afchain vor flexible anclor elemente? Which is adjust'w ably 'connected With an anchor-device to be now described." yThis 'anchor device extends longitudinally of the -stall and 'embodies a bas'ef'plate, which is bolted or otherwise rigidly'secured totheledge') of the floor ofjthefstall. This base plate is provided at one end With L-shaped members or knuckles 59', ladapted tou receive therebenea-th "a transverse'head 60,1formed upon an upper bar 61. This-"upper fbar has aA series of openings or notches'f'62; spaced longitudinally oiv the same, for receiving the lowermost link of' passing through a knuckle on the bar 61. It

is thusseen that the upper and lower con.- nections for the stanchion may be adjusted longitudinally of the stall.
